I currently have a set of ADVMosster driving lights mounted in the front of my bike over the wheel and under the headlights with a PIAA mount kit. I'm only partially satisfied with them. They seem to not extend my brights lights very much. I am considering changing them out for either a Denali DR1 or D2 lights to replace them. I am planning to use one flood lens and one spot lens to get more light both down the road and close to the bike. I am also interested in using the DataDim feature of the lights. Has anyone traded out a set of inexpensive Chinese 10W LEDs for either of these? Does anyone know if the D1s will fit under the fairing and not interfere with the front fender when the front shock compresses? The ads say the DR1s are 3.75 inches in diameter. I intend to put these lights on the PIAA mount.
